I was looking at the acugage system, one draw back was the fact that it has 3 wires going from the tank to the panel vs the WEBA I'm replacing that only as 2. Called up the nice people at Snake River Electronics to ask what type of wire I needed to fish from my holding tank to the panel. Their tech guy said I didn't need to run a new wire. Piggy-back the nutural from any 12 volt source near the tank. Rework the current nutural to be the other wire they need for their system. Since all the nutural wires go directly to the same place on the nutural bar there is no problem. I wired a house years ago and an electricina told me to do the same thing then, forgot that trick during the last 20+ years. Now if the unit I ordered and had sent express was here rather than in Paris and on its way to Casablanca I'd be all set. Boy do I hate FedEx right now. Russell Russell
